Solved the problem that logon is still displayed when users add comments after logon.

The answer is getting closer and closer. In the afternoon, add content to the configuration! As the content is filled in, I find that there are a lot of things to be changed. The layout, layout, and color matching of the page have to be taken into consideration again. I feel that the time is really tight, and there is also a PPT. use case diagram to do it, i'm so dizzy!
The biggest headache is that it still shows logon when users add comments after logon. I also asked laruence for help in major forums, but I did not solve it! Then try to do breakpoint debugging! I found that the session is null when I click the comment to go To the redirection page! Adjusted the bool value!
If (session ["blog"]! = NULL) ------ change here
{
Blogvo BVO = (blogvo) session ["blog"];
If (BVO! = NULL)
{
Power. Text = "<a href = \"/blog/admin/default. aspx \ "> management </a> ";
}
Else
{
Power. Text = "<a href = \"/blog/login. aspx \ "> login </a> ";
}
}
Else
{
Power. Text = "<a href = \"/blog/login. aspx \ "> login </a> ";
}
